| Summary: | This paper presents a method for determining the outgoing line with a singlephase fault for 6–35 kV networks with a non-sinusoidal loads. The paper considers
the relevance of applying the mathematical apparatus of the wavelet transform
together with the traditional methods of fault location. The application of the
wavelet is relevant in the problems of decomposition of non-sinusoidal current
signal of outgoing lines. This is due to the loads of modern enterprises of the oil
producing sector of Khanty-Mansiysk Autonomous Okrug–Yugra. It is proposed
to modernize the existing algorithm for relative measurement of the level of higher
harmonics. The proposed method makes it possible to determine the outgoing
line by the total energy of the spectrum of higher harmonics for different network
configurations. |
